I can't check right now, but I think the contributing section in the manual 
describes this. You might want to have a look :)

To list leaf packages that are affected by a change (and the number of packages 
affected, including non-leaf), you can use guix refresh:

guix refresh -l foo

Will tell you which leaf packages are affected if you modify foo. Build them 
all if the number is low. If the number of dependents is high enough to qualify 
for staging or core-updates, then checking only some of them is ok.

Yes, if the package is important to you, please file a bug report with details 
about the failing build, to bug-guix. Don't bother upstream :)

We have ci.guix.gnu.org, which is our build farm. You can use the search box to 
look for failing builds.

If you manage to fix some of them, definitely send a patch!
